Short summary
We report on the development of a new laminar flow tube reactor for the study of gas-phase atmospheric chemistry and secondary organic aerosol formation. The present paper is devoted to the design and fluid dynamical characterization of the reactor. The results of gas and particle residence time distribution experiments in the reactor, together with an evaluation of the effect of non-isothermal conditions, are reported.
